J. L. MONTGOMERY SHADE SUPPORTING BRACKET Filed m rch 17. 1926 Patented Apr. 10, 1928.

UNITED STATES JOHN L. MONTGUMERY, OF STONEHAM, MASSACHUSETTS.

SHADE-SUPPORTING BRACKET.

Application filed March 17, 1926.

This invention relates to a. shade-support ing bracket and is herein shown as embodied in a bracket of the character shown and described in U. S. Patent No. 1,321,233 granted to me November 11, 1919.

The present invention has for its object to provide a shade-supporting bracket with separate members'for engaging the shadeelevating cords, whereby both lifting cords may be located in close proximity to each other and substantially parallel, for a purpose as will be described.

The cord-engaging members are preferably made as rollers which for convenience may be designated main and auxiliary rollers, the main roller being cent-rally located with respect to the height of the bracket, and the auxiliary roller may be located above or below the main roller, preferably below the latter.

The bracket is constructed as will be described to carry these rollers.

The particular features of the invention will be pointed out in the claims at the end of this specification.

Fig. 1 is an elevation of a sufficient portion of a window provided with an adjustable shade and with supporting brackets therefor, one of which embodies the present invention' Fig. 2, a detail showing the improved bracket secured to the inside of the casing;

Fig. 3, a side elevation of the bracket shown in Fig. 2 looking toward the left;

Fig. 4, a plan view of the bracket shown in Fig. 2, and

Fig. 5, an elevation of the bracket secured to the outside of the casing.

The invention is shown as embodied in a bracket of substantially the same general construction as that shown in the patent referred to, and comprises a metal back plate 10, top and bottom flanges 12, 13 provided with holes 30, 31 in vertical alignment,

' side flanges 14, 15, an intermediate flange 17 struck up from the plate 10 to form the opening 16 and which co-operates with the side flange 15 to form bearings for the shaft 20 of a grooved roller 21.

The back plate 10 is provided with holes for the passage of screws 22 when the back plate is fastened to the casing 23 on the inner side thereof as shown in Fig. 1.

The flange 17 in the present instance is located substantially midway of the height of the back plate 10 and is made relatively Serial No. 95,438.

narrow to enable the bracket to be provided with lugs or cars 25, 26 above and below the flange 17 and extended substantially at right angles thereto and substantially parallel with the back plate 10. I

Each of the lugs or cars 25, 26 co-operates with the back plate 10 so as to form bearings for the shaft 34 of a grooved roller 35 if so desired, but in the present instance only one shaft 34 is supported by the lug 26, which is located below the shaft 20 of the roller 21.

The two lugs or cars 25, 26 enable the bracket to be reversed when so desired or required. For convenience, the roller 21 may be designated the central roller and is designed to be used with the main lifting cord 36 for the curtain roller 37 One end of the cord 36 is connected with the sliding bearing member 38 for one end of the shaft 39 of the curtain roller 37, and said cord is passed upwardly and over the central roller 21 of the bracket affixed to the left hand side of the window casing as shown in Fig. 1, and is then carried across the Window to the right hand bracket and passed over the central roller 21 and is then carried down to near the bottom 40 of the window casing and fastened to a cleat 41 or otherwise.

This arrangement of the main lifting cord 36 is the same as shown and described in the patent above referred to.

The sliding bearing member 42 for the right hand end of the shaft 39 of the curtain roller 37- has connected with it one end of an auxiliary lifting cord 43 which is passed upwardly and over the auxiliary roller 35 and then downward and has its other end fa stened at 44 to the main cord 36.

By providingthe bracket with the auxiliary roller 35 arranged substantially at right angles to the roller 21, a separate cord-engaging member is provided for the auxiliary lifting cord 43, and the latter is enabled to be brought into close proximity to the main lifting cord 36 and to assume a substantially vertical position as clearly shown in Fig. 1.

This construction and arrangement enables this character of bracket to be used with curtains of standard width in new Work and more particularly in what is known'as replacement work, in which curtains which are pulled down are converted into curtains which are lifted.

By means of the improved bracket herein shown, this conversion of the pulled-down curtain to one which is lifted, can be effected without narrowing the width of the curtain or the length of the curtain roller, because of the vertical arrangement of the auxiliary lifting cord andits proximity to the main lifting cord, and to the window casing when the bracket is secured within the window casing as represented in Fig. 1.

The new bracket is also useful with old curtains and curtain rollers when applied to the outside of the window casing a shown in Fig. 5, for it can be fastened to the window casing in the same position thereon which was occupiedby the old bracket.

It is preferred to provide the bracket with two lugs 25, 26 above and below the central roller, as this construction enables the bracket to be reversed and used on either the right or the left side of the window and said bracket may be provided with an auxiliary roller above or below the central roller, or the bracket ma be provided with two auxiliary rollers if desired and either one used, but it is not desired to limit the invention in this respect.

It is preferred however to provide the bracket with two lugs or ears 25, 26, and to use only one auxiliary roller, preferably with the lug below the central roller.

It is preferred to use rollers as the cordengaging members, as the friction is materially reduced thereby, but it is not desired to limit the invention in this respect.

The bearing members 38, 42 for the curtain roller 37 slide on rods 50 whose upper ends extend into the hole in the flange 12 or 13 according to the position of the bracket, as described in the patent referred to.

Provision is made for retaining the cord 43 in operative relation to the auxiliary roller under all conditions of use and especially when said cord is slack. To this end, the top and bottom flanges 12, 13 are provided with extensions or fingers 60 which are extended so as to overlap the lugs 25,

26 and close the space between the said lugs and the top and bottom flanges and thereby confine the auxiliary lifting cord &3 in the space between the roller 35 and the top or bottom flange 25 or 26 adjacent to said roller, and prevent said cord when slack from riding off of the roller and over the lug 25' or 26.

The invention is shown as embodied in a preferred form of bracket, but it is not desired to limit the invention to the particular construction shown.

What is claimed is:

1. A shade-supporting bracket comprising a back plate provided with a side flange having lugs spaced apart and extended therefrom substantially parallel with said back plate and having an opposing side flange and a flange extended substantially parallel with said side flanges and located between said lugs, a roller supported by said flanges, and a second roller supported by one of said lugs and said back plate and arranged substantially at right angles to the first-mentioned roller.

2. A shade-supporting bracket comprising a back plate provided with a side flange hav ing a lug extended, therefrom substantially parallel with said back plate and having an opposing side flange and a flange extended substantially parallel with said side flange between the same, a cord-engaging member supported by the intermediate flange and one of said side flanges, and a cord-engaging member supported by said lug and back plate and arranged substantially at right angles to the first-mentioned cord-engaging member.

3. A shade-supporting bracket comprising a back plate provided with a side flange having a lug extended therefrom substantially parallel with said back plate, a cord-engaging member supported by said lug and back plate, and a flange extended from said back plate and provided with an extension co.

operating with the said lug to close the space between the cord-engaging member and the last mentioned flange.

In testimony whereof, I have signed my name to this specification.

JOHN L. MONTGOMERY.
